I don't know if any email provider would handle such a large file, but it is possible to put them all together. Simply make a New Folder, then put all the pages into that folder. The Folder could then be sent as a single zip file, it would still contain all the pages.

It's probably caused by the limit your estate agent has on their inbox. There are a couple of solutions:

1. Stick your HIP on a CD and send/give it to them.2. Upload it to some webspace and let them download it. As it's a ZIP file it will download when the link is clicked on.3. Split the file into smaller parts and email those parts to the estate agents a few at a time. One of my favourite file Splitters is called JASP. JASP produces a .bat file which when you double click all the separate files will be merged into the original file, have all the files, including the .bat file, in one folder. click here
